Step-by-step explanation:
Charlie is making chocolate cake for his birthday party. He found a recipe that needs 2 cups of cocoa powder for every 3 cups of sugu. Al of his friends
are coming, so he uses 6 cups of cocoa powder in his cake,
How many cups of sugar should Charlie uso?
Step-by-step explanation:
the mix follows the ratio 2/3 (cups of cocoa to sugar).
2 × x = 6 cups
x = 6/2 = 3
so, the cocoa cups number is multiplied by the factor 3, and we need to multiply also the sugar cup number with the same factor to keep the ratio value unchanged :
so, we need 3×3 = 9 cups of sugar.
Write an equation in slope-intercept form of the line that passes through the given point and is parallel to the graph of the given equation
(-9,- 4); y = - 3x + 5
Write an equation for the line in slope-intercept form
(Simplify your answer. Use integers or fractions for any numbers in the equation)
Step-by-step explanation:
the general slope intercept form is
y = ax + b
a is the slope. a parallel line must have the same slope.
in our case here it is -3.
b is the y-intercept (the point, where the line crosses the y-axis, meaning the y value when x=0).
we get b by using the point coordinates in the equation and solve for b :
-4 = -3×-9 + b = 36 + b
b = -40
so, the full equation of the parallel line is
y = -3x - 40
Find the cost per roll if a bag of five lunch rolls is $2.50
[tex]\rule{300}{3}[/tex]
[tex]\text{Hi!}[/tex]
To find the cost per item (or in your case "rolls"), you will first have to divide the cost of the lunch rolls [tex](2.50)[/tex] by the amount of lunch rolls there are [tex](5)[/tex].
So in this case, it would look like
[tex] \textbf{$2.50/5} [/tex][tex]\text{$2.50 ÷ 5}[/tex][tex]\text{$2.50 / 5}[/tex][tex]\text{2.50}[/tex] ÷ [tex]\text{5}[/tex]

Answer:
a. 3/10
b. 1/5
c. 1/4
Step-by-step explanation:
a. 30/100 = 3/10
b. 20/100 = 1/5
c. 25/100 = 1/4
Answer:
Step-by-step explanation:
You are working with 1 large square made up of 100 little squares. The little squares make up 10 columns of 10 little squares each.
A
Shaded part = 30 squares.
Entire large square = 100 small squares
% = 30 / 100 * 100 = 30%
B
Shaded part = 20 horizontal squares.
Entire large square = 100 small squares
% = 20 / 100 * 100 = 20%
C
Shaded part = 5 by 5 little squares = 25 little squares
Entire large square = 100 small squares
% = 25 / 100 * 100 = 25%

Find the inverse (pre-calc)
Answer:
f^(-1)(x) = e^(x/3)
Step-by-step explanation:
1. Replace 'f(x)' by 'y:' y = 3ln x
2. Interchange x and y: x = 3ln y => x/3 = ln y
3. Solve for y:
e^(x/3) = y
4. Replace this 'y' with 'f^(-1)(x)'
Then f^(-1)(x) = e^(x/3)
Jason was a recent graduate from a university program with a Bachelor of Science in Medical Technology. He will begin a position at the local hospital working 40 hours a week with an hourly rate of $25.50. He will receive a paycheck every two weeks. In a document, calculate the following. Be sure to show your mathematical calculations.
Gross Pay for 1 paycheck
Deductions for federal tax, state tax, and city tax
Deduction for F.I.C.A. or social security tax
Deduction of $117 for medical and dental insurance.
What would Jason’s net monthly income and net annual salary be after taxes and insurance?
Answer:
Gross Pay for 1 paycheck
Deductions for federal tax, state tax, and city tax hope it helps :)
Step-by-step explanation:
The net monthly income of Jason is $194.68 and the net annual salary is 23324.16.
What is gross pay?Gross pay of an employee is basically sum of his basic pay, dearness allowance, any other allowance only. Public providend fund, income tax are not deducted from it.
How to find net pay?1) Gross paycheck=2*40*25.5=$2040.
2) Federal tax=2040*21%=$428.4
3) State tax=25=$25
4) City tax=2040*12%=$244.8.
5) Deductions=2040*12.45=$252.96.
6) Net monthly income=2*(Gross pay-federal tax-state tax-city tax-deductions-deductions for F.IC.A. or social security tax)
=2*[2040-428.4-25-244.8-252.96-117]
=1943.68
7) Net annual salary=12* net monthly income.
=1943.68*12 ( 1year= 12 months)
=$23324.16
Hence the net monthly income of Jason is $194.68 and the net annual salary is 23324.16.

What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
18 ounces. of iced tea costs 2.99. Then the ratio of cost to weight is calculated as,
⇒ $2.99 / 18
⇒ $0.166 per ounce
Then the cost of 30 will be calculated as,
⇒ $0.166 x 30
⇒ $4.98
The cost of 30 ounces of iced tea will be $4.98.
